一个简易的时间显示器

 1 function clock() {
 2     var today = new Date();
 3     var days = today.getDay();
 4     var day = today.getDate();
 5     var month = today.getMonth();
 6     month += 1;
 7     var year = today.getYear();
 8     year += 1900;
 9     var hour = today.getHours();
10     var minute = today.getMinutes();
11     minute = ms(minute);
12     var second = today.getSeconds();
13     second = ms(second);
14     document.getElementById("time").innerHTML = year + "年 " + month + "月 " + day + "日 星期" + days + " " + hour + ":" + minute + ":" + second;
15     setTimeout("clock()", 1000);
16 }

18 function ms(x) {
19     if (x < 10) {
20         x = "0" + x;
21     }
22     return x;
